To all whom it may G01/wem:

Be it knownl that f1, FRANK Gnanrrnn, l a citizen of vthe United States,residing at Duluth, in the county of St. Louis-and State of 'Minnesota,have invented new and useful Improvements in'Drags, of which thefollowing is a specification.

rlhis invention comprehends the: provision of a circular drag-whichenables the latter to be used close toand around atree, stump or postwithout catching in thev latter, and is also constructedto 4free itselffrom'stones, weeds, roots or the like,which:tend to clog the drag as thesaid drag is capable of turning to leave the weeds 'orthe'like behindwithout stopping or interfering with the progress ofthe team.

Another object of the invention resides in providing a structurewhichall'ows the team and drag to be turned around without 1causing thechai-n traces to strike the legsof the animal which frequently happensand: results in bad sores on the animalslegs.v

The nature and advantages of the invention 'will be better understoodwheny the fol lowing detailed description is read in connection with theaccompanying drawings,

the invention residing in the construction,

combination and arrangement of parts as claimed.

In the drawing forming part of this application, like numerals ofreference indicate similar parts in the several views, and whereinFigure 1 is a plan view of the drag. Figure 2 is a sectional viewtherethrough. The drag forming the subject matter of the presentinvention is circular in contouras clearly illustrated in Figure 1, andis preferably made in two sections which are pivotally connectedtogether as at 10, so that it can be advantageously used in smallravines or hills in the field, one section being capable of independenttilting movement with relation to the other. Each section includes innerand outer curved members 11 and 12 respectively which are connected byradially disposed pieces 13, and depending from these curved members andalso from the radial pieces 13 are teeth 14. A draft bar 15 is pivotedas at V16 at a point approximately in the center of the drag, and thisconstruct-ion manifestly allows either the draft bar to be turned in anydirection with relation to the drag, and also allows the drag to beturned on its pivot with relation tothe draft bar. It is due to thisconstruction that the :advantages-above 'outlined are accomplished.Surrounding the drag and spaced frointhe outer members 12 is combinedguard railrafnd track made up yin two sections 17, the ends of which arepivotally connected together 'as yat 1S in alignment with the pivotslO'ofthe respective sections, so that thefguar'd rail 17 can be broken inalignment 'with the pivots 10 when one secn tion is tilted with relationto the other. The guardrail is supported by brackets 18 arranged inla,circumferential series and secured to the underside of the outermembers 12 of the respective sections, The draft bar is spaced a slightAdistance above the dragy topermit freedomv of movement thereof,onthe*pivot`16,andcarried by the said bar adjacent the outer end thereofis a pair of spaced pulleys 19 which engage the inner and outerperiphery of thev guard rail 17, to guide the draft bar in its movement.l By reason of the construction rshownanddescribed, it ismani'fest-'thatthe dragl can' be worked `close/Co a stu-mp, post for tree withoutcatching in the latter, and also worked around such obstructions withoutthe latter interfering with the progress of the team attached thereto.In other words, the guard rail 17 will strike t-he object, and becauseof the fact that the drag is capable of turning on a pivot 16 it willwhirl about, and accomplish its work without being checked by the postor the like. Then again due to this circular movementof the drag, thelatter cannot become clogged with weeds, roots or bunches of grass,because when it .gets overloaded with such matter it will make acomplete circle leaving them behind. So that the team can continue topull the drag over the groundor surface without being stopped orotherwise interfered with by stones or other objects above referred to.Furthermore, it is due to the fact that the drag and draft' bar arepivotally connected at the center, that the drag can be turned around atany place in the lield without the chain traces strikingagainst the legsof the team which is a common occurrence with square drags, and usuallyresults in bad sores on the legs of the animal. With the presentinvention the drag and teamfcan be turned around without the chainscoming in contact with the legs of the animal. Furthermore, one of thepulleys 19 is capable of adjustment toward and away from the otherpulley through a slot 20 in that portion of the draft bar with which thepulleys are associated, the pulleys being maintained in proper workingposition by means of nuts 2l.

The outside pulley is made adjustable as stated, and as clearly'illustrated in the drawing, so that the draft bar can be lifted up fromthe drag when desired, and to compensate for wear of either of thepulleys or the drag. The invention will operate more efficiently whenthe pulleys are prop- `erly adjusted to allow the draft bar to slidealong the track freely, for if too much play is allowed between thepulleys and the track, the dra-ft bar will be very apt to pull away fromthe latter rendering the invention practically useless forthe purposeintended. All of this howeveris overcome by having one of the pulleysmounted for adjustment toward and away from the track as shown.

lVhile it is believed that from the foregoing description, the natureand advantagesof the invention will be readily apparent, I desire tohave it understood that I do not limit myself to what is herein shownand described, and that such changes may be resorted to when desired asfall within the scope of what is claimed.

Having thus described the invention, I claim:

l.A A circular drag comprising a pair of hingedly connected sections,teeth depending from each section, a circular guard rail surrounding thedrag and spaced therefrom,

and including` pivotally connected sections, means for supporting therail on the drag, and a draft bar having one end pivoted centrally ofthe drag.

2. A circular drag comprising a pair of hingedly connected sections,teeth depending from each section, the guard rail surrounding said dragand spaced therefrom, and including pivotally connected sections, meansfor supporting the guard rail on the drag, and a draft bar having oneend pivoted centrally on said drag, and spaced pulleys carried by saidbar and engaging the inner and outer periphery of said guard rail forguiding the bar in its movements as described. A

3. A circular drag comprising a pair of hingedly connected sections,each section including inner and outer curved members, radially disposedstrips connecting said members, teeth depending from the members andstrips of each section, a guard rail surrounding the drag and spacedtherefrom and including pivotally connected sections, a plurality ofbrackets including the guard rail on said drag, and a draft bar havingone end pivoted centrally in said drag, and a pair of adjustable pulleyscarried by said bar adjacent the outer end thereof and engaging theinnerand outer periphery of saidvguard rail. p

In testimony whereof I affix my signature.

FRANK CHARTIER.
